SPECIFICATION forming part of Letters iatent No. 736,332, dated August 11, 1902;.

. Application filed December 15,1902. Serial No. 135,239. (No model.)

useful Milk-Cooler, of which the following is a specification.

My object is to provide a simple, strong, durable, and efficient portable device specially adapted for advantageouslyextracting animal heat from milk that is designed to be used for dairy purposes.

My invention consists in the construction and combination of flat tubes with a tank, a

flat chamber, a fixed cover for a vessel, and a delivery-tube and faucet, as hereinafter set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which- Figure 1 is a side elevation of my invention, that shows the forms and relative positions of the different parts. Fig. 2 is a transverse sectional view on the line a: so of Fig. 1, that shows the flat tubes and the delivery spout and faucet in a plane above the fixed cover for vessels in which the main and lower portions of the tubes may be placed to contact with milk. Fig. 3 isa transverse sectional view on the line y 3 that shows the fiat tubes so arranged relative to each other as to mutually brace each other, as required to prevent any lateral fiexion or bending out of perpendicular lines.

The numeral 10 designates a water-tight sheet-metal tank that may vary in size,as desired. A plurality of fiat open-ended sheettubes12 are fixed in corresponding apertures in the bottom of the tank to communicate therewith. To the lower end of the flat tubes is fixed a fiat sheet-metal chamber 13,adapted to serve as a foot to support the complete device in a perpendicular position when it is placed on 'a shelf, floor, or table, and also adapted for increasing the 1 radiating surface that is to impart the temperature of cold water to milk that contacts therewith, as required to expelother they mutually brace and support each other and strengthen the complete device.

To the upper end portions of the fiat tubes 12 is fixed a disk or cover lat, adapted to serve as a means of suspending the fiat chamber and tubes .in a common milk-tank or other suitable vessel in which milk may be placed, and also adapted to close the top of such a vessel, as required to prevent extraneous matter from falling into the milk in the vessel. Perforations in the cover allow ventilation and the escape of animal heat that is extracted from the milk during the process of cooling it in the vessel.

To the central portion of the closed top of the flat chamber 13 is fixed a flat tube 15 to communicate with the chamber, and its top extends up through the cover 14 and terminates in a delivery-spout 16, that extends therefrom at right angles and has a faucet 17 on its free end.

In the practical use of my inventionwhen warm fresh milk has been placed in a suitable can, tank, or vessel and the milk-cooler placed in the milk and suspended therein by means of the fixed cover 14 cold water is filled in the water-tank 10 and allowed to fill and circulate through the plurality of flat tubes 12 and the flat chamber 13 and to rise through the central fiat tube 15 to be dis charged through the horizontal delivery-tube 16 and faucet 17 in a plane above the vessel upon which the cover 14: is placed for suspending the milk-cooler in a vessel and also closing the top of the vessel. The cold tem* perature of the water is thus imparted to the milk as required to cool the milk.

It is obvious ice and ice-water may be placed in a vessel and warm milk or other liquid may be poured in the water-tank l0 and allowed to circulate through the fiat tubes and chamber at their lower ends to quickly and advantageously cool it by means of my convenient portable device. It is also obvious that-by providing means for closing the outer end of the tube 16 water or milk may be advantageously retained at times in the tank 10 and tubes 12 and 15 and carried about therewith.

Having thus described the purpose of my invention and its construction and operation,

tank, a plurality of fiat open-ended tubes fixed in the bottom of the tank in right-angled position to each other and a fiat Watertight chamber fixed to the bottom ends of the fiat tubes, a fiat perforated cover fixed to the top portions of the tubes and a fiat openended tube fixed t0 the top and central portion of the fiat chamber and extended up through the fixed perforated cover and then at right angles, and means for opening and closing said tube, arranged and combined in.

the manner set forth for the purposes stated.

2. A portable device for cooling milk and other Warm liquids, comprising a Water-tight tank, a plurality of flat open-ended sheetmetal tubes fixed in the bottom of the tank, a flat Water-tight chamber fixed to the bottom ends of the fiat tubes, a flat disk or cover fixed to the upper portions of the flat tubes, a fiat open-ended tube fixed to the top and central portion of the top of the Hat chamber, a lateral extension at the top of said central tube and a faucet on the end of the extension, arranged and combined as shown and described to operate in the manner set forth for the purposes stated.
